As you know, I've been blogging about the evolution of White hat SEO for over 3 years now. Cassie found this awesome video compilation from SES in London and it seemed post-worthy if you are trying to figure out exactly what Black Hat SEO really is? They posed the questions "What should we do with the Black Hat SEOs?" Notice how many of the responses are along the lines of "learn from them" or "take what they are doing and tone it down a bit so it's gray hat."
